I have started dating a guy (for the past month). We hit it off brilliantly, there is a real spark. I know it's very early days and we are just 'dating' at this point as opposed to being in a relationship but he is very keen and affectionate towards me and we bounce off each other so well. We were chatting about someone I know who is having an affair and I asked him if he had ever cheated on a partner to which he replied 'Yes, I have actually. The relationship was dead, it was right at the end and I had an affair with a married woman.' I asked if he felt guilty on his partner (of six years) and he said, 'No, not at the time'. I was put off by him. Not only because he would have an affair but also because he didn't seem particularly remorseful. He is the kind of person who seems to be very truthful and won't hide things and I guess everyone has a past but not everyone will admit to the things that are unpleasant about that past.
He seemed quite surprised when I said I'd never and would never be unfaithful to a partner. The problem for me is that he seems to be such a nice, caring guy and I find the thought of just walking away based on this one thing difficult. He has also told me that they were not really compatible and were more like friends. I generally tend to assume, though, that if someone's unfaithful once there's a good chance they will be again.
I'm interested to know if this is a 'Run for the hills' situation for most people or whether most would just try to overlook and gauge how our relationship develops or doesn't.
